I admit I'd fully never heard of this symptom before, but apparently it's not uncommon—thanks to increasing (and normal) levels of testosterone, women can experience vocal changes...including deeper, raspier voices.

Says Kristen: "There was something more 'Mommy' about my voice and we had to fix it [for the movie]. I certainly didn’t intend that, and when you heard it, you couldn’t really place why it was different but it was. It was one of those hormonal things that happen, I guess."
